A imigração e a língua de acolhimento em Portugal: questões de identidade e integração

A imigração, a diversidade e a multiculturalidade estão cada vez mais presentes nas sociedades modernas e a gestão desta realidade representa um enorme desafio, tanto para as sociedades de acolhimento como para os próprios imigrantes. Esse desafio implica um processo de adaptação e integração que apenas pode funcionar havendo vontade e esforço de ambas as partes envolvidas. O país (sociedade) de acolhimento deve trabalhar no sentido de promover um ambiente onde nativos e imigrantes possam conviver pacificamente garantindo a todos o respeito por direitos e deveres, bem como pelas suas identidades. Quanto aos imigrantes, têm que se adaptar a uma nova vida e uma nova realidade longe dos seus países de origem, devendo também eles respeitar o meio em que se encontram e do qual passam a fazer parte, ao mesmo tempo que tentam preservar as suas identidades e os laços com o seu país de origem. É um processo que envolve muitas mudanças, particularmente para os imigrantes. O país, a sociedade, os costumes, a cultura, o clima, as crenças, a língua, etc, fazem parte de um conjunto de novas experiências e novas aprendizagens para o imigrante. Essas novas experiências trazidas pela imigração têm a potencialidade de gerar mudança identitária. Através de um estudo que pretendeu dar voz aos próprios imigrantes, procurei neste trabalho perceber se há realmente mudanças ao nível da identidade provocadas pelo processo de imigração e de que modo atuam alguns elementos nessa mudança e no processo de integração, nomeadamente a língua – língua materna e língua de acolhimento.Abstract: Immigration, diversity and multiculturalism are every day more present in the modern society and dealing with this reality represents a big challenge for both, host society and the immigrants. It requires a process of adaptation and integration that can only work if both parts are involved and willing to make things work. The host society must promote an environment where natives and immigrants can live together peacefully and also guarantee that all legal rights and obligations are respected as well as people’s identities. When it comes to the immigrants, they have to adapt to a new culture and environment, making sure they respect the society which they are now part of, and also try to preserve their identities and the bound with their own country and people. It's a process that involves many changes, more so to the immigrants. The nation, society, habits, culture, weather, beliefs, language, etc., are all new experiences to them. These integration and experiences could have the potential to generate identity changes. Through a study that wanted to listen to the immigrants opinions and experiences, I’ve tried to understand if there are actually changes in immigrants identities as a result of the migration process and how do some elements take place in that change, particularly the language - language from the host society and language from the origin country

Analysis Of Population Health in Relation to Drinking Water After Quality In Murmansk Oblast

Introduction. Drinking water is one of the most important environmental factors that determines human health, which requires a search for causal relationships between drinking water pollution and increased incidence of the population. Materials and methods. We studied the incidence level of the Murmansk Oblast (Russia) population with diseases associated with the drinking water quality. We also analyzed the drinking water quality, and calculated the carcinogenic risk associated with the intake of pollutants from drinking water. Results. The risk areas in terms of drinking water quality are the city of Kirovsk and Pechenga district, the priority pollutants of drinking water are aluminum and nickel. In Pechenga district, there is an increased incidence of the blood diseases, digestive organs, nervous system, skin and subcutaneous tissue, as well as female infertility. The highest incidence rates of malignant neoplasms are recorded in the city of Murmansk. Conclusions. The aluminum role in the formation of the incidence level in the Kirovsk city population has not been established. The nickel impact on the health of the Pechenga district population may be associated with the development of female infertility and the development of contact dermatitis, in case of cutaneous action. However, the other risk factors contribution, including exposure to nickel and its compounds in the professional activities framework, needs to be clarified. The carcinogens influence present in drinking water on the additional cases formation of malignant neoplasms in Murmansk Oblast seems to be negligible

Mass generation with adjoint fermions

The QCD-like gauge theory with adjoint fermions is considered in the field correlator formalism and the total spectrum of mesons and glueballs is obtained in agreement with available lattice data. A new state of a white fermion appears, as a bound state of the adjoint fermion and gluon with the mass close to that of glueball. It is shown, that the main features of spectra and thermodynamics of adjoint fermions can be explained by this new bound state.Comment: 19 page

Deuteron frozen spin polarized target for nd experiements at the VdG accelerator of Charles University

A frozen spin polarized deuteron target cooled by the 3He/4He dilution refrigerator is described. Fully deuterated 1,2-propanediol was used as a target material. Deuteron vector polarization about 40% was obtained for the target in the shape of a cylinder of 2 cm diameter and 6 cm length. The target is intended for a study of 3N interactions at the polarized neutron beam generated by the Van de Graaff accelerator at the Charles University in Prague

Integrable systems on the sphere associated with genus three algebraic curves

New variables of separation for few integrable systems on the two-dimensional sphere with higher order integrals of motion are considered in detail. We explicitly describe canonical transformations of initial physical variables to the variables of separation and vice versa, calculate the corresponding quadratures and discuss some possible integrable deformations of initial systems.Comment: 19 pages, LaTeX with AMS font

Quantitative description of lifting and ignition of organic fuel dusts in shock waves

The Lagrangian mathematical model taking into account the Saffman and aerodynamic interaction forces and based on surrounding film approach is suggested for the description of dust particle lifting and ignition in the gas flow field. On the basis of this model the initial stage of lifting of single particle in the dust-laden layer is adequately described. The model is verified by the comparison with the experimental data on trajectories, dependencies of ignition delay time of the coal particle on the gas temperature behind the shock front

CARIES PROPHYLAXIS: JUST ANOTHER MYTH OR REALITY?

Due to the fast (and drastic) changes of the oral care products market in Russia for the last 15–20 years, it's become feasible to evaluate the efficiency of caries fluorine prophylaxis. Despite the wide usage of fluorine content toothpastes, the rates of caries among children haven't actually changed. Moreover, in some regions a growth of frequency and intensity of this pathology has been witnessed, especially in younger age groups. At the same time, the introduction of new prophylaxis programs results in reduced rates of caries (decrease by 60–70%). This open wide opportunities for successful and efficient prophylaxis programs for kids and teenagers — both within organizations (schools, kindergartens, colleges) and individually by doctor's recommendation.Key words: children, caries, prophylaxis

Regularities of oil spilled oil transformation in watercourses and coastal zone (results of long-term observations). International Multidisciplinary Scientific

International audienceThe present paper is devoted to the results of long-term field observations of oil pollution transformation in small watercourses of the Lower Don River basin (Russia), on the Atlantic coast of France and in the Strait of Kerch polluted by spilled oil. The investigations included visual assessment and sampling of oil slicks, water and sediment cores. The analysis of samples were carried out with the use of thin layer and column chromatography, optical and gravimetric methods making possible to determine separately the sum of saturated, mono- and di-aromatic hydrocarbons (HC), the sum of polycyclic aromatic hydrocarbons (PAH) and the sum of asphaltic components (AC) as well as the presence of hydrocarbons of contemporary biological origin. In the course of time it’s revealed an exponential decrease in the oil pollution level and in the ratio between hydrocarbons and asphaltic components (HC/AC). We suggest that the ratio HC/AC can be considered as a simplified indicator of the oil pollution transformation level as it takes into account only qualitative pollutant changes and is not considerably influenced by dilution, migration and other mechanical factors. In the studied cases the values of half-period of oil pollution transformation varied from 350 to 6930 days. The highest activity of natural cleansing process was observed on the exposed rocky shores, sandy and gravel beaches and riverine sectors with coarse sediments, rapid water flow and high oxygen saturation.The statistical analysis of the results of long-term observations enabled the authors to quantify the influence of principal geographical factors on the rates of natural cleansing process. This information is used to develop an innovative methodology of estimation of water ecosystems’ natural cleansing ability
